Bug#487176: linux-image-2.6.18-6-686: open sleeps
Package: linux-image-2.6.18-6-686
Version: 2.6.18.dfsg.1-18etch5
Severity: important
Hello,
[I just sent this as an email to linux-fsdevel@vger.kernel.org, however as it
involves the kernel in Debian/Etch, I felt it wise to submit here too. Upstream
may not be happy with supporting the older kernel version...]
I am having (weird) issues with XFS, in that open(...) on certain files takes
45 seconds to return. After the file has been opened, the next file in the same
directory takes 45 seconds. If the file was recently opened it returns
immediately.
I thought this was a low level I/O issue, so copied the files in question to a
completely independent RAID array (separate LVM, RAID, controllers, disks), but
the problem remains.
I raised the issue on the XFS mailing list and was told the problem was the the
lease breaking code in VFS[2], and that I should contact this mailing list.
This is with the kernel in Debian/Stable:
hq:/tmp# uname -a
Linux hq 2.6.18-6-686 #1 SMP Sun Feb 10 22:11:31 UTC 2008 i686 GNU/Linux

Any ideas?
